Yeah, actually. I have a wired and wireless apple keyboard, and you can pop all the keys out, soak them in dish detergent or something to get gunk out of those, and use various tools such as q-tips and such to clean the bottom part out. Quite efficient, in my experience. Just be sure to pop the shift and spacebar keys back with the metal in the right place. Not too complicated. I think there's a few other keys with metal wire in them too, same thing. I imagine any other keyboards are similar.

You shouldn't need to pop any key-caps to get under the keyboard. It's got three hex-head screws on the bottom. They're very small, and I've never found a tool the right size, but it looks like removing the screws should allow the keyboard to lift out of the transparent tray.
